Regional Weather Summary
National Weather Service State College PA
446 AM EST Fri Dec 9 2016
A broad and very cold upper level trough extending across the
Great Lakes and Southeastern Canada will remain in place for the
next few days. This weather feature and a well-aligned westerly
flow off the Great Lakes will bring a prolonged period of Lake
Effect Snow and significant snow accumulations to Northwestern
Pennsylvania today through Saturday. Mostly cloudy to cloudy
skies with a brisk wind and scattered snow showers will occur
elsewhere across the Central Ridge and Valley region of the state
today through Saturday.
High temperatures today will range from the mid 20s across the
northwest mountains and the Laurel Highlands, to around 40 degrees
in the Philadelphia area. Lows early Saturday will vary from the
upper teens to low 20s across the mountains, and mid 20s
throughoutthe Susquehanna River Valley.
High pressure will bring a brief period of clearing and tranquil
conditions as it builds northeast across the commonwealth late
Saturday and Saturday night, causing the Lake Effect snow bands
to lift north of the region. Afterward an area of low pressure
will track east from the Ohio Valley and impact Pennsylvania with
another bout of Wintry Weather Sunday into Monday.
